5. Physically check that the Bit is secure before
operating. The Bit will have approximately 1-3/4"
of play, but should not come out when pulled.
Note: During extended operation, periodically remove
the bit and re-lubricate the loading end with grease.
Workpiece and Work Area Set Up
1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. Secure loose work pieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
If working in the ground or on a concrete slab
on the earth, call local utility company to
ensure that area is clear of utility lines.
5. Protect power cord from crushing, abrasion,
and scraping by broken rock or concrete.
6. Keep power cord away from moving machines.

General Operation

TO PREVENT SERIOUS INJURY:
Wear ANSI-approved safety goggles, ear protection,
steel-toe boots, and dust mask during use.
Keep feet clear of Breaker Hammer.
Keep children and animals well
clear of the work area.
1. Check Bit for dullness, cracks, or other damage.
CAUTION! Dull tipped bits can cause unnecessary
bit movement, resulting in tool wear and
possible injury. Use only sharp tipped bits.
2. Clearly mark the work area.
3. Make sure that the Trigger is in
the off-position, then plug the tool into an
outlet on a circuit rated to 20 amps.
4. Set the bit against the work area.
CAUTION! Keep power cord away
from moving machines.
5. Place one hand on the Side Handle and
the other hand around the Main Handle.

Note: Trigger does not lock. Keep pressure
on the Trigger to keep running the tool.
7. Push the tip forcibly down to begin striking material.
NOTICE: Running tool with no load or "empty
blows" will damage the Breaker Hammer.
CAUTION! Once activated, do not press,
bear down, or thrust forcibly against the work
surface. Allow the Breaker Hammer's own
weight to supply the needed force.
Note: If the Breaker Hammer has not been used for
a long time or is being used in low temperatures,
the tool may require 3-5 minutes to warm up.
NOTE: Carbon Brushes will wear during use.
The Breaker Hammer will stop working if the
Brushes are worn. This does NOT mean Breaker
Hammer is malfunctioning or broken, only that the
worn Brushes will need to be replaced with the
included Brushes by a qualified technician.
8. When work is complete, release the Trigger.
The Trigger is spring-loaded and will return
to the off position automatically.
9. To prevent accidents, turn off the tool and
disconnect its power supply after use.
10. Clean, then store the tool indoors
out of children's reach.
